The only network I often use when I have a transaction is BSC, Trx, and Solana. I rarely use it, but it is also fast compared to BSC and Trx, according to my observation.
But as far as I know, Solana is also often experiencing congestion in the network, followed by Ton, and sometimes it's BSC, but it also rarely happens.
In the bitcoin network, it's not fast, although sometimes there are times when it's fast. but usually not really.
